Can someone double check my tire size tune? I had the height at 30.6 but I could be off and seems like the speedo is off.
Thank you

That tire size is 30.6, so if you put it in there it should be right.
Did you auto scale the trans files when you did it??
Use a tire size calculator to compute the stock tire size and the new tire size. Add or subtract the difference between the two sizes to the size in the stock calibration. This is a more accurate way of calibrating the speedometer. Stock tire size height in the calibration will almost always be smaller than what a tire size calculator says.
